Description

We report new ALICE measurements of inclusive charged-particle jet suppression and jet azimuthal anisotropy in Pb--Pb collisions. Inclusive charged-particle jet spectra in central Pb--Pb collisions at $\sqrt{s_{\mathrm NN}}$ = 5.02 TeV are measured over a broad kinematic range, including to very low jet $p_{\mathrm{T}}$, with jet resolution parameter up to 0.5, using event-mixing to correct uncorrelated background. The first measurement of inclusive charged-particle jet yield in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.36 TeV, based on high-statistics Run 3 data, are reported differentially as a function of event-plane orientation, to measure jet azimuthal anisotropy $v_{2}$. The resulting distributions of nuclear modification factor and $v_{2}$ probe jet quenching in regions of phase space that have not been explored previously. Comparison of these measurements to theoretical calculations provide new insight into the mechanisms underlying jet quenching.
